Get up to speed on Scala, the JVM language that offers all the benefits of a modern object model, functional programming, and an advanced type system. Packed with code examples, this comprehensive book shows you how to be productive with the language and ecosystem right away, and explains why Scala is ideal for today's highly scalable, data-centric applications that support concurrency and distribution. This second edition covers recent language features, with new chapters on pattern matching, comprehensions, and advanced functional programming. You’ll also learn about Scala’s command-line tools, third-party tools, libraries, and language-aware plugins for editors and IDEs. This book is ideal for beginning and advanced Scala developers alike. Program faster with Scala’s succinct and flexible syntax Dive into basic and advanced functional programming (FP) techniques Build killer big-data apps, using Scala’s functional combinators Use traits for mixin composition and pattern matching for data extraction Learn the sophisticated type system that combines FP and object-oriented programming concepts Explore Scala-specific concurrency tools, including Akka Understand how to develop rich domain-specific languages Learn good design techniques for building scalable and robust Scala applications

If you have an imperative (and probably object-oriented) programming background, this hands-on book will guide you through the alien world of functional programming. Author Joshua Backfield begins slowly by showing you how to apply the most useful implementation concepts before taking you further into functional-style concepts and practices. In each chapter, you’ll learn a functional concept and then use it to refactor the fictional XXY company’s imperative-style legacy code, writing and testing the functional code yourself. As you progress through the book, you’ll migrate from Java 7 to Groovy and finally to Scala as the need for better functional language support gradually increases. Learn why today’s finely tuned applications work better with functional code Transform imperative-style patterns into functional code, following basic steps Get up to speed with Groovy and Scala through examples Understand how first-class functions are passed and returned from other functions Convert existing methods into pure functions, and loops into recursive methods Change mutable variables into immutable variables Get hands-on experience with statements and nonstrict evaluations Use functional programming alongside object-oriented design
